Pristidae
Sign in to saveSawfish, also known as carpenter sharks, are a family of very large rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish, with some species reaching lengths of about . They are found worldwide in tropical and subtropical regions in coastal marine and brackish estuarine waters, as well as freshwater rivers and lakes. All species are critically endangered.
OverviewAI-generated
Pristidae is a family of sawfishes within the order Rhinopristiformes, class Elasmobranchii, and phylum Chordata. The taxon was described by Bonaparte in 1835 and is currently accepted. It is distinct from the family Pristiophoridae. Common names for the group include pexe xerra and pilarji.
Members of this family inhabit marine, brackish, and freshwater environments. The lineage dates back to approximately 100 million years ago. Pristidae is listed in Appendix I of CITES. Records of the family have been documented in the United States, Morocco, and Egypt, with specimens held by institutions such as ROM, CUMV, NMMNHS, NHMUK, and UCMP.

Sägefisch ist eine Weiterleitung auf diesen Artikel. Für die Typusart siehe Gewöhnlicher Sägefisch. Für die Schlüsselmaschine mit diesem Decknamen siehe Siemens & Halske T52. Sägerochen (Pristidae (Gr.: „pristis“ = Säge)), oft auch Sägefische genannt und von den Sägehaien zu unterscheiden, sind Rochen, die einen eher gestreckten, haiähnlichen Körper haben. Ihr auffallendstes Merkmal ist die "Säge", ein knorpeliger, seitlich mit Zähnen besetzter Auswuchs des Kopfes, der mehr als 25 % der Gesamtlänge der Fische ausmachen kann. Die Säge dient dem Beutefang. Dazu schwimmen die Tiere in Fischschwärme und schlagen dann mit der Säge hin und her, um anschließend die verletzten Opfer zu fressen. Weiterhin wird sie benutzt, um in schlammigem Boden nach Weich- und Krebstieren zu wühlen. Die Säge dient auch als Sinnesorgan für elektromagnetische Signale, um Beutetiere aufzuspüren.

Sawfish, also known as carpenter sharks, are a family of very large rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish, with some species reaching lengths of about . They are found worldwide in tropical and subtropical regions in coastal marine and brackish estuarine waters, as well as freshwater rivers and lakes. All species are critically endangered.
They should not be confused with sawsharks (order Pristiophoriformes) or the extinct sclerorhynchoids (order Rajiformes) which have a similar appearance, or swordfish (family Xiphiidae) which have a similar name but a very different appearance.
